Description
The DSC PRM-4W Polarity Reversal Module is designed for use with the FSA series of 2-wire and 4-wire smoke detectors and smoke alarms with integral sounders. This module enables tandem connection, ensuring that when one smoke detector goes into alarm, all connected detectors will sound their horns simultaneously for maximum safety and awareness.
When the control panel enters alarm mode, it signals the PRM-4W to reverse the power polarity supplied to the smoke detectors. This polarity reversal activates all integral horns, creating a unified alert across the entire system. Compact, reliable, and built for integration, the PRM-4W is an essential addition for interconnected smoke alarm functionality in security and fire systems.
